The firstsemiconductor device 1 may receive or output first to fourth dataDQ<1:4>. The first to M^(th) command signals CMD<1:M>, the first toN^(th) address signals ADD<1:N>, and the first to fourth data DQ<1:4>may be transmitted through lines that transmit at least one group ofaddresses, commands and data. The numbers ‘M’ and ‘N’ of bits of thefirst to M^(th) command signals CMD<1:M> and the first to N^(th) addresssignals ADD<1:N> may be set to be natural numbers. Although FIG. 1illustrates an example in which the number of bits of the first tofourth data DQ<1:4> is set to be four, the present disclosure is notlimited thereto. For example, the number of bits of the data may be setto be different from four according to the embodiments.

The control circuit 10 may generate a control signal WCTR and first andsecond shifting signals SFT<1:2>, if the first to N^(th) address signalsADD<1:N> having a certain combination are inputted to the controlcircuit 10 by a predetermined number of times or more according tocombinations of the first to M^(th) command signals CMD<1:M> during awrite operation.

The first to eighth internal dataID<1:8> may include the first to fourth correction data ECD<1:4>, thefirst and second parity signals ECP<1:2>, and the first and secondshifting signals SFT<1:2>. An operation that the data conversion circuit22 shifts the first to fourth correction data ECD<1:4> and the first andsecond parity signals ECP<1:2> to generate the first to eighth internaldata ID<1:8> in response to the control signal WCTR will be describedlater. The positions of the first to fourth correction data ECD<1:4>,the first and second parity signals ECP<1:2>, and the first and secondshifting signals SFT<1:2> included in the first to eighth internal dataID<1:8> will be described in later.

The secondsemiconductor device 2 may restore the positions of the first to fourthdata DQ<1:4> and the error information of the first to fourth dataDQ<1:4> stored in the page in response to the first to M^(th) commandsignals CMD<1:M> during the read operation. The second semiconductordevice 2 may correct the errors of the first to fourth data DQ<1:4>using the failure information to output the corrected data in responseto the first to M^(th) command signals CMD<1:M> during the readoperation.

Referring to FIG. 2, the control circuit 10 may include a counter 11, acontrol signal generation circuit 12, and a shifting signal generationcircuit 13.

The counter 11 may generate first to third counting signals CNT<1:3>which are counted whenever the first to N^(th) address signals ADD<1:N>having the certain combination are inputted to the counter 11. FIG. 2illustrates an example in which the counter 11 is a single counter, butthe counter 11 may be configured to include the same number of countersas the pages to estimate the sameness of various combinations of thefirst to N^(th) address signals ADD<1:N>. FIG. 2 illustrates an examplein which the number of bits of the first to third counting signalsCNT<1:3> is set to be three, the present disclosure is not limitedthereto. For example, the number of bits of the counting signals may beset to be different from three according to the embodiments.

An operation of the counter 11 will be described more hereinafter inconjunction with an example in which the first to N^(th) address signalsADD<1:N> having the certain combination are inputted to the counter 11four times.

If the first to N^(th) address signals ADD<1:N> having a certaincombination are inputted the counter 11 four times, the counter 11 maycount up the first to third counting signals CNT<1:3> having a logic lowlevel (L) to generate the first counting signal CNT<1> having a logiclow level (L), the second counting signal CNT<2> having a logic lowlevel (L), and the third counting signal CNT<3>having a logic high level(H). The counter 11 may be realized using a general counter generatingthe first to third counting signals CNT<1:3> which are counted up orcounted down whenever the first to third counting signals CNT<1:3>having the certain combination are inputted to the counter 11.

The control signal generation circuit 12 may generate the control signalWCTR including a pulse which is generated whenever the first to thirdcounting signals CNT<1:3> are counted a predetermined number of times ormore, in response to the first to M^(th) command signals CMD<1:M> duringthe write operation.

For example, the control signal generation circuit 12 may generate thecontrol signal WCTR including a pulse which is generated when the firstto third counting signals CNT<1:3> are counted four times. In addition,the control signal generation circuit 12 may generate the control signalWCTR including the pulse which is generated whenever the first to thirdcounting signals CNT<1:3> are counted up four times or more. That is,the control signal generation circuit 12 may generate the control signalWCTR including the pulses which are generated when the first to thirdcounting signals CNT<1:3> are counted four times, five times, six timesand seven times.

The shifting signal generation circuit 13 may generate the first andsecond shifting signals SFT<1:2> which are counted whenever the first tothird counting signals CNT<1:3> are counted a predetermined number oftimes or more. The first and second shifting signals SFT<1:2> mayinclude shifting information of the first to fourth correction dataECD<1:4> and the first and second parity signals ECP<1:2>.

For example, the shifting signal generation circuit 13 may generate thefirst and second shifting signals SFT<1:2> which are sequentiallycounted up from a point of time that the first to third counting signalsCNT<1:3> are counted four times. The shifting signal generation circuit13 may generate the first and second shifting signals SFT<1:2> which arecounted up when the first to third counting signals CNT<1:3> are countedup four times, five times, six times and seven times.

For example, if the first to third counting signals CNT<1:3> are countedfour times, the shifting signal generation circuit 13 may generate thefirst shifting signal SFT<1> having a logic low level (L) and the secondshifting signal SFT<2> having a logic low level (L). If the first tothird counting signals CNT<1:3> are counted seven times, the shiftingsignal generation circuit 13 may generate the first shifting signalSFT<1> having a logic high level (H) and the second shifting signalSFT<2> having a logic high level (H).

Referring to FIG. 3, the data conversion circuit 22 may include a latchcircuit 221 and a register 222.

The latch circuit 221 may shift the first to fourth correction dataECD<1:4> and the first and second parity signals ECP<1:2> in response tothe pulse of the control signal WCTR. The latch circuit 221 may outputthe shifted first to fourth correction data ECD<1:4>, the shifted firstand second parity signals ECP<1:2>, and the first and second shiftingsignals SFT<1:2> as first to eighth latch data LD<1:8>. The latchcircuit 221 may restore storage positions of the first to fourthcorrection data ECD<1:4> and the first and second parity signalsECP<1:2> to output the restored data and the restored parity signals asfirst to sixth output data DO<1:6> based on the first and secondshifting signals SFT<1:2> included in the first to eighth latch dataLD<1:8> during the read operation.

The register 222 may output the first to eighth latch data LD<1:8> asfirst to eighth internal data ID<1:8> in response to a write signal WTwhich is inputted during the write operation. The register 222 mayoutput the first to eighth internal data ID<1:8> as the first to eighthlatch data LD<1:8> in response to a read signal RD which is inputtedduring the read operation.

A write operation of the semiconductor system according to an embodimentof the present disclosure will be described hereinafter with referenceto FIG. 5 in conjunction with an example in which a predetermined numberof times that the first to N^(th) address signals ADD<1:N> having acertain combination are inputted is set to be four and a total number oftimes that the first to N^(th) address signals ADD<1:N> having thecertain combination are inputted is set to be five during the writeoperation.

First, if the write operation starts, the first semiconductor device 1may output the first to M^(th) command signals CMD<1:M> and the first toN^(th) address signals ADD<1:N> for executing the write operation (see astep S1). At this time, the first to N^(th) address signals ADD<1:N>having the certain combination may be outputted from the firstsemiconductor device 1 five times.

Subsequently, the number of times that the first to N^(th) addresssignals ADD<1:N> having the certain combination are inputted may bedetected, and the detected number of times may be compared with fourcorresponding to the predetermined number of times (see a step S2). Ifthe detected number of times is less than four, the write operation maybe executed and may terminate (see steps S4 and S5). If the detectednumber of times is five, the counter 11 of the control circuit 10 maycount up the first to third counting signals CNT<1:3> five times togenerate the first counting signal CNT<1> having a logic high level, thesecond counting signal CNT<2> having a logic low level, and the thirdcounting signal CNT<3> having a logic high level.

The control signal generation circuit 12 of the control circuit 10 maygenerate a pulse of the control signal WCTR at a point of time that thefirst to third counting signals CNT<1:3> are counted up four times(corresponding to the predetermined number of times) and may generateanother pulse of the control signal WCTR at a point of time that thefirst to third counting signals CNT<1:3> are counted up five times, inresponse to the first to M^(th) command signals CMD<1:M>. That is, thepulse of the control signal WCTR may be generated twice.

The shifting signal generation circuit 13 of the control circuit 10 maycount up the first and second shifting signals SFT<1:2> to generate thefirst shifting signal SFT<1> having a logic high level and the secondshifting signal SFT<2> having a logic low level, at a point of time thatthe first to third counting signals CNT<1:3> are counted up five times.

The error correction circuit 21 may detect errors of the first to fourthdata DQ<1:4> and may correct the errors of the first to fourth dataDQ<1:4> to generate the first to fourth correction data ECD<1:4> and togenerate the first and second parity signals ECP<1:2> including errorinformation on the first to fourth data DQ<1:4>.

Subsequently, since the pulse of the control signal WCTR is inputtedtwice, the latch circuit 221 of the data conversion circuit 22 mayoutput the first parity signal ECP<1>, the second parity signal ECP<2>,the first correction data ECD<1>, the second correction data ECD<2>, thethird correction data ECD<3>, the fourth correction data ECD<4>, thefirst shifting signal SFT<1>, and the second shifting signal SFT<2> asthe first latch data LD<1>, the second latch data LD<2>, the third latchdata LD<3>, the fourth latch data LD<4>, the fifth latch data LD<5>, thesixth latch data LD<6>, the seventh latch data LD<7> and the eighthlatch data LD<8>, respectively (see a step S3).

That is, as described with reference to FIG. 4, the first to sixth latchdata LD<1:6> may be generated by shifting the first to fourth correctiondata ECD<1:4> and the first and second parity signals ECP<1:2> twice,and the seventh and eighth latch data LD<7:8> may be generated to be thefirst and second shifting signals SFT<1:2>.

Subsequently, the register 222 of the data conversion circuit 22 mayoutput the first to eighth latch data LD<1:8> as the first to eighthinternal data ID<1:8> in response to the write signal WT (see the stepS4).

The memory area 30 may store the first to eighth internal data ID<1:8>in a page which is selected by the first to N^(th) address signalsADD<1:N> (also see the step S4).

Subsequently, the write operation may terminate (see the step S5).

The semiconductor system having an aforementioned configuration mayshift storage positions of the data and the parity signals and may storethe data and the parity signals into the shifted storage positions toenhance the reliability of the parity signals, if a certain page isselected a predetermined number of times or more to store the data andthe parity signals into the certain page. In addition, since the storagepositions of the data and the parity signals are shifted and the dataand the parity signals are stored into the shifted storage positions,degradation of memory cells storing the parity signals whose errorsoccur more frequently than the data may be prevented.

The buffer memory 1003 may temporarily store the data which areprocessed by the memory controller 1002. That is, the buffer memory 1003may temporarily store the data which are outputted from or to beinputted to the data storage circuit 1001.
